Hylexin for "serious dark circles"

Has anybody ever tried the eye cream, Hylexin? It's about $95.00 a tube USD and sells at upscale department stores as well as online for same price. I wouldn't say I have "serious" undereye circles but I do have circles. It's also supposed to tighten the skin and there's a 30-day money-back guarantee when unused portion is returned. I guess I have nothing to lose if I can get my money back, right?

I have a friend who worked for a plastic surgeon, and she told me that no product can eliminate dark circles under the eyes. I wish that were not true! I've always had them--it's hereditary, and already I can see my 11 year-old daughter has them, too. When I was in high school, people were already asking me if I was tired because of these darned circles! I use concealer.
